Jan 13 2017 JLEIC Ion Integration Meeting (and Notes)

• Yuhong presented a strong cooling parameter update at the Jan 12 2017 JLEIC R&D Meeting.
• This included some substantial impacts on a broad set of parameters for JLEIC.
• Rui is also starting to develop a work and priority plan for impedances/instabilities this calendar year.
• Discuss and set out objectives for next few months:

Ion Source R&D at LBNL

• Mike was at LBNL for an 88-inch cyclotron ops review this past week
• One item worth noting is their ECRIS ion source R&D for VENUS and MARS.
• We will briefly discuss any possible implications. Note that Amy came to us from LBL!

AOB

• Last meeting we noted the following -- progress?
• Yves is working with Rui and others to start developing an impedance budget -- progress?
• This partly uses ZAP for some calculations, but some calculations (e.g. IR region beampipe) require calculations with approximate expected geometry.
• Todd is also concerned about BPM designs for the collider ring with long and short bunches (before and after splitting).
• Vasiliy noted that Roman Pots in the ion collider ring at $\approx 10\sigma$ may also have significant impedance impact.
• Tim notes that an engineering team is starting to assemble to evaluate integration needs, e.g. power supply/magnets. BPM and instrumentation design may be part of this.

• TBD
